Codebase Mapping

Overview

Auto-indexes the project structure to build a comprehensive codebase map. This map is used for invisible context injection via the UserPromptSubmit hook, providing Claude with project awareness without explicit user prompting.

Map Contents

Project Structure

  • Directory tree with depth-limited enumeration
  • Key file identification (entry points, configs, lock files)

File Type Distribution

  • Language breakdown (TypeScript, JavaScript, Python, etc.)
  • Framework detection (React, Next.js, Express, etc.)

Entry Points

  • Main entry files (index, main, app)
  • CLI entry points
  • API route definitions

Module Dependencies

  • Import graph analysis
  • Package boundary mapping
  • Circular dependency detection

Test Layout

  • Test directory structure
  • Test file patterns and conventions
  • Test framework identification

Context Injection

The codebase map is injected as invisible context during UserPromptSubmit, providing:

  • Project type and framework awareness
  • Convention awareness for code generation
  • Dependency awareness for import suggestions
  • Test pattern awareness for test generation

When to Use

  • Automatically at ClaudeKit session start
  • When project structure changes significantly
  • Before research or specification tasks

Processes Used By

  • claudekit-orchestrator
    (session initialization)
  • claudekit-research
    (context for research agents)
  • claudekit-spec-workflow
    (context for spec creation)
